AGV goes in the wrong direction

KSugai — Fri, 19 Apr 2024 05:23:02 GMT

[ FlexSim 24.0.3 ]

In the attached model, AGV is given the task of traveling from CP0 to CP1. After running the simulation, for some reason it moves in the direction of CP3 instead of CP1.

When I changed the reset position and destination of AGV, this phenomenon occurred only in the above pattern.

The following two conditions seem to be necessary for this phenomenon to occur.

・Reset position of AGV is on an intersection.

・Destination is adjacent to reset position of AGV.

Please tell me how to avoid this phenomenon.

This seems like a bug to me. I will let the developers know.

I tried a few different things to see if I could figure out what it is going on, and the only workarounds I have found so far are:

1. Move CP0 so it is not on the intersection.

2. Adjust path3 (between CP0 and CP3) so it comes into the intersection at an angle - so it is not completely perpendicular to path1. Adjusting the angle of path1 also does the same thing.

Update: Upon further investigation, this issue can only be avoided by creating a control point on a specific path and using that control point as the AGV's start point. While the behavior is strange, it occurs when an AGV's start point is on an intersection, which should be avoided.
